Is there a concern that extended OA is going to allow the mites to build resistance like they have everything else. The beautiful thing about OA vapor is it only stays in the hive for. 48-72 hours. It has been an effective treatment for a really long time. Yes it has its short comings, but has never lost its effectiveness.
So far there is no indication that mites have developed resistance to oxalic acid; however, you are correct in stating that so far they have been applied as flash/quick treatments. So for now, it will be best to follow label instructions and rotate among difference active ingredients/products.
Oxalic acid attacks via a weak point, mites have sticky feet, allowing access to their "blood". Too much acid absorbed into blood bypasses any evolutionary mechanism for digestive or metabolic compensation. Also, plants have used oxalic acid as oxalate for many millions of years as chemical defense. Same for thymol. Both which bees tolerate as strict plant feeders. Blood/fat sucking specialized parasites ... not so much.
There was one study done on long term treatment with OA dribble. Dr. Matías Maggi compared the susceptibility to oxalic acid between two Argentinian mite populations: One that had been exposed to 64 consecutive treatments of oxalic acid dribble (8 times a year for 8 years) as the sole mite treatment, vs. A control population that had never been exposed to beekeeper-applied organic acids (the beekeeper had used coumaphos, flumethrin, or amitraz in a rotation scheme). He found that the oxalic-exposed mite population didn’t exhibit any sign of resistance-in fact, it surprisingly appeared to actually be more susceptible to oxalic than the oxalic-naïve population. This is good news, since it suggests that whatever the mode of action of oxalic acid is against mites, that it’s not easy for them to develop resistance.
Is this the product Kaymon Reynolds is talking about, saying it doesn't reduce the number of mites in your hive it just holds them steady, not allowing them to increase in number?
So do I understand that if you’re running double deeps or double mediums then you don’t place strips per every two frames in the upper boxes? Please clarify. Thanks.

Will Vita compensate Randy Oliver for the work he has done with this idea?
It’s Argentina 🇦🇷 idea not Randy Oliver

Why is there a hive dangling over his head?
It's a bird feeder :)
Is he a native Spanish speaker. If so can you do this video again but in Spanish
Yes, he does speak Spanish. Thanks for your suggestion and we will look into adding more languages moving forward.
They'll do everything to avoid selecting for mite tolerant bees. Pathetic really.
Oh great. You can go treatment free then and save your money. Just keep your bees away from mine 😂
@@nszucs1 typical beekeeper.

Here you are again complaining and trolling Bruce! How boring and predictable.
@@kamonreynolds you again. So try pointing out what I said that was false.
